Abstract (en)
[origin: EP3561093A1] The present invention relates to a Ni-based heat-resistant alloy including Ir: 5.0 mass% or more and 50.0 mass% or less, Al: 1.0 mass% or more and 8.0 mass% or less, W: 5.0 mass% or more and 25.0 mass% or less, and balance Ni, having an L1<sub>2</sub>-structured γ' phase present in the matrix, and including at least one of Zr: 0.01 mass% or more and 3.0 mass% or less and Hf: 0.01 mass% or more and 3.0 mass% or less. This Ni-based heat-resistant alloy has improved toughness over a conventional Ni-based heat-resistant alloy based on a Ni-Ir-Al-W-based alloy, and is also excellent in ambient-temperature strength.
